3) RDF object is always literal. Can't directly reference

what are the workarounds?
The workaround is to specify an URI as a literal and hope software
understands this in cases like linking archive contents.
I miss the whole discussion, but RDF objects in statements are either
literal, blank nodes, or URIs.
like this (turtle syntax):
<file://home/dirk/blub.txt> nie:myExampleUri <http://exampleuri>.
<file://home/dirk/blub.txt> nie:myExampleString "Unterzögersdorf".
Yes, but xesam decided to limit objects to literals only(as well as other
limitations) and lift them only if it is necessary.
That is xesam is fully RDFS-compliant, yet we implement the smallest necessary
subset of it for performance, coding complexity and other considerations.
you need datatypes for String, boolean, DateTime and Float anyway,
adding URL won't hurt much.
btw, to throw them in here, perhaps somebody needs them
here are the links to the relevant other standards, I am currently
writing a document for something else and gathered them. They use
string, boolean, datatime, float.
